Ratio of bioluminescence to bacterial numbers for Pseudomonas fluorescens 5RL attached to titania. All data are significantly different (p < 0.01) comparing respective conditions of nanophase to conventional titania

Titania formulation	Photons/sec/cells/cm2
Conventional with phosphate buffer	0.074
Conventional with glucose	0.081
Nanophase with phosphate buffer	0.091
Nanophase with glucose	0.099
